IMPROVED BEVELJAWED VISE.

`The Schedule referred to in these-Letters Patent and makng'part ofl theaantne To all whom it may concern Be it known that I, AUSTIN ZdvlAsoN,of Adrian, `in the county of Lenawee, and State ot' Michigan, `haveinvented certain new and useful Improvements in Vises, the same beingimprovements upon the improved vise for which Letters Patent were issuedto Aus'rlN Z. MASON, February 6, 1869, No. 92,337

` and Ido hereby declare that the following is a full,

clear, and exact description ofthe same, reference being had to theannexed drawings, making part of this specification, like lettersreferring to similarparts.

p The object of this invention is to simplify the con-v struction of theabove-mentioned vise by les'seuing the number and modifyingA the formofthe parts used.

In the drawings- Figure l isa side elevation of a vise embodying myinvention.

i Figure 2 is an elevation of' the same, showing the -Figure 5 is a viewof the parts represented when l seen in the direction of the arrow z, intig/ 1. i Figure 6 is a sectional view cutting the line X Yin iig. 2,and showing a plan of the vise.

F representsthe movable jaw cfa common wooden vise; the stationary jaw,being .the same as those in common use, is not represented.

D is an iron `hed-piecescrewed fast to the movable jaw F. i r

i B is an adjustable iron facefplate. 'lhe sident' thebed-piece D, shownin iig. 3, is to be placed next to the.. recessed face of the ironfaceplate B, and there held` by the bolt' W, as shown in fig. 6. y n

A` is a wooden wedge-shaped face secured to the` adjustable ironface-plate B, to be used when the vise is to beemployed for clampingwooden pieces, and to he removed, ii' desirable, `when it is intended touse the vise for clamping iron pieces.

Theadjustable face-plate B, figs. 4 and 6, is a dat,

square disk of iron, having two fulcra, m and n, which parts of thesocket are brought together.

Across the upper end of this face-plate B a flange or edge is turned upto a uniform height, as shown at B, g. 6, and from this flange anotherextends in like manuel' downward upon the edges of the plate B,diminishing its projection, as it descends, as shown bythe dotted lineh, in lig. 6, until it is vlost at the bottom edgein the surface of theplate.

In the center of this face-plate B is a ball and socket which joins theface-plate B to the bed-piece D, being held together by theballheadedbolt W, nut t, and coiled spring c, iig. 6.

rlhis socket-joint is shown in a seqtional view in y6, and is thereshown how the lower end of the wood face A may be thrown in toward themovable A jaw F,

by clamping a wedge shaped piece with the thick end downward, the fulcram and n preventing horizontal movement around the socket.

This socket-joint is made up by throwing up the conical-shaped ring N,iigs. 4 and 6, upon the face-plate B,and inserting it in a similar ring.thrown `up from the outer face of the bed-piece D.

The ball-headed bolt W is first passed through the openin g in thebottom of the conical ring N, and then the 'face-plate B fastened to thewooden face A b screws, as represented. i

The bolt is then passed through lthe square open-A ing in the center ofthe conical ring H, figs. 3 and6, and then the coiled wire springeslipped around the bolt up against the back of the bed-piece D, andthenut t screwed up against the coiled spring; the object of this springbeing to give uniform tension to the turning of the face-plate.

lher-bed-piece Dis made to fit into the recess in Ithe face-plate B, sothat by crowding the lower end tion, the socket-joint H N causing thewooden face-l plate A to conform readily to the angle of the piececlamped.y

When the face-plete B is turned to the position shown in figs. `1 and 6,the vise above the socket-joint becomes a solid parallel vise; and asthe face-plate is turned to the right or left by quarters ofarevolution, the solid-parallel will be correspondingly turned,

The opening g in the lower end ot' the face-plate and wooden face is forthe purpose of bringing it successively over the Screw-holes 1 2 3 4, inth bedpiece, when a screw-driver may be inserted to drive the screwsthat fasten the bed-piece to thc movable jaw F.

inasmuch as theoice of -the socket-joint H N is B. ROBBINS,

simply to form a pivot around which the face-plate B may turn, and alsoallow, at the same time, a rocking motion over the fulcra m and n, it isevident that :L single common bolt may be used to perform thatfunctiomthereby dispensing with the use of the socketjoiut altogether.

I do not, therefore, wish to limit myself to the use of the sockeikjointalone, but to use a. bolt in its stead, if desirable.

l claim as a-u improvement on t-he vise patented to me July 6, 1869, No.92, 331- The omission of the plate C, described in said patent, and theconstruction herein described of the plates B and D, and the arrangementof' the seme on the vise-jaw, substantially as and for the purpose setforth.

AUSTIN Z. MASON.
